In the technical scheme, when the device addresses are sequentially allocated to the online devices according to the second sequence, the first start address is firstly acquired. The first start address may be a preset start address, or an address may be manually designated by an installer as the first start address. After the first start address is determined, according to a preset address determination rule, a plurality of device addresses behind the first start address can be obtained, and a first device address sequence containing the plurality of device addresses is generated. The device at the head of the second sequence is assigned a first start address and subsequent devices in the second sequence are sequentially assigned subsequent device addresses in the first sequence of device addresses until all devices are assigned independent device addresses.

and step S206, sequentially allocating the device addresses to the devices in the second sequence according to the second sequence and the first device address sequence.
When the online equipment is sequentially allocated with the equipment addresses according to the second sequence, the first starting address is firstly acquired. The first start address may be a preset start address, or an address may be manually designated by an installer as the first start address. After the first start address is determined, according to a preset address determination rule, a plurality of device addresses behind the first start address can be obtained, and a first device address sequence containing the plurality of device addresses is generated. The device at the head of the second sequence is assigned a first start address and subsequent devices in the second sequence are sequentially assigned subsequent device addresses in the first sequence of device addresses until all devices are assigned independent device addresses.

Specifically, if some devices are not powered on simultaneously when the system is powered on for the first time, after the device addresses are allocated to the more powered devices in the second sequence, the second start address is determined according to the device addresses of the devices located at the tail of the column. Specifically, the second start address, even if located in the second sequence column, is the next address of the device address determined according to the preset address determination rule.

Wherein, for some embodiments, the device address is a numeric address, i.e., the device address is represented as a number or a combination of numbers. In the second sequence, the address of any one device is the sum of the number of devices preceding it, the sum of the values corresponding to the first starting address.
For example, if the first start address is "0", that is, the value corresponding to the first start address is 0, the device addresses of the devices in the 6 th sequence position in the second sequence satisfy: 0+5 is 5, i.e. the device address of the device located at the 6 th sequence position is "5".

In this embodiment, the system detects the total number of devices in the second sequence in real time, that is, the total number of devices present, and obtains the number of devices on line in the system at the same time, and if the number of devices on line is smaller than the total number of devices, it indicates that there may be a problem of address duplication of part of devices. At this time, the device address set of the devices on line is transmitted to each device. When any equipment receives the equipment address set and finds that the equipment address corresponding to the equipment is not in the equipment address set, the equipment judges that other equipment is duplicated with the equipment address of the equipment, randomly generates corresponding prompt information and sends the prompt information to a system, and the system marks the equipment as address duplication equipment.
